The rack-bar and the lever with its accompanying bellcrank lever and dog are of the usual and ordinary construction in this class of m achines and need no further description here. 28 indicates links, the upper ends of which are pivotally connected with the lower ends of the levers 27 and the lower ends bent into a ring adapted to encircle the lower cranks of the doublecrank levers 18 19. By means of the links 28 the cultivator-beams may be raised from the ground directly by the vibration of the lever in the usual manner. In case, however, that it is not desired to use the lever, but the operator wishes to raise the cultivator-beams from the ground by the action of the foot levers 18 19, the hand-lever 27 is locked in its position upon the rack-bar. By the pressing of the feet of the operator downward and forward upon the upper cranks of the doublecrank levers 18 19 the cultivator beams and blades will be raised from the ground in' the same manner as hereinabove described, the link 28 performing the same function as the spiral springs 23 with their accompanying links 25, and the parts when raised will assume the same position, as shown by the dotted lines in Fig. 2, and the beams are held suspended in that position.

It is obvious that with the devices and construction shown in Fig. 4: the hand-levers 27 may, if the operator desires, be used to cooperate with the action of the foot-levers in raising the cultivator beams and shovels from the ground.

In either of the above constructions, when it is desired to lower the cultivator-beams by v the action of the double-crank levers, such forward end.

levers are rotated upward by the feet of the operator and the operation above described for raising the cultivator-beams is reversed.

To adjust the seat of the cultivator I use the following devices: 29 indicates castings, which are bolted or otherwise secured to the braces 6 7. The castings 29 are provided with pins 30 31, projecting horizontally inward, said pins 31 being somewhat lower than the pins 30. 32 indicates a seat-beam, which is provided with spreading forked arms at its The forward ends of the arms of the seat-beam are provided in their upper surfaces with one or more notches 33, which are adapted to engage with the'pins 30 31, and the seat-beam passing backward rests upon the upper surface of the arched axle 8. 34 indicates a seat which is slidingly mounted in the ordinary way upon the rear portion of the seat-beam When it is desired to adjust the position of the seat-beam, the notches 33 are freed from engagement with the pins upon which they may rest and adjusted to the other pins, as may be desired. Referring to Fig. 3, the solid lines show the seat-beam in a lower position, the notches 33 being engaged with the pins 30. The dotted lines show the seatbeam brought forward, so that the notches 33 are engaged with the pins 31, thus moving the seat forward and raising it.

I have shown in the drawings, in Figs. 1 and 2, the upper and forward end of the spring hung upon notched arms. The pur pose of using the notched arms is to adjust the tension of the springs by changing the spring from one notch to another, it being obvious that the farther forward the spring is hung the greater will be the tension. This is the method in which I prefer to connect the springs with the framework or braces 6 7; but it is obvious that the springs might be suspended directly from the framework. l have also shown in Figs. 1 and 2 a spiral spring and links connecting the double crank lever with the framework, and in Fig. 4 a link connecting the lower end of the hand-lever with the double-crank lever. It is obvious, however, that so far as the opera tion of the double-crank lever is concerned a link like that shown in Fig. 4. might be used in place of the springs and links shown in Figs. 1 and 2, and also that springs and links like those shown in Figs. 1 and 2 might be used to connect the lower end of the hand-lever 27 with the doublecrank lever, it being esseutial to the working of the double'crank lever only that it should be connected with the frame.

It is also obvious that whether springs and links such as are shown in Figs. 1 and 2 are used or only a single link is used the operation and function of the device are to suspend the beams of the cultivator in their hung-up position. The operation of the double-crank levers 18 19 when acting as a hang* up device is clear from Fig. 2. It will be seen that when the cultivator-beams are lowered the foot-arm of said double-crank lever extends upward and the arm with which the spring or link is connected is forward of the bearing 21. As the foot-arm of the doublecrank lever is brought down, the cultivatorbeam is raised, as above described, until the double-crank lever is rotated through alittle more than half a circle. At this point the parts assume the position shown by dotted linesin Fig. 2, in which it will'be seen that the connecting-point of the link with the double-crank lever is behind and somewhat above the pivotal point or bearing 21 of said lever, and the line of the link and spring is above a line drawn from said pivotal point to the point of suspension of said spring and link on the frame, causing the'beam to be supported in its hung-up position. When the line of the link and spring comes above a line drawn from the pivotal point to the point of suspension of said spring and link to the cultivator-frame, the operation of the spring and link is to support the beam in its hung-up position; but when the double-crank lever is rotated so that the line of the spring and link falls below a line drawn from the pivotal point of said link to the-point of suspension of said link and spring to the cultivator-frame the cultivator-beams will fall by their own weight.

It is also obvious that when the springs are used they must be of sufficient stiffness or tension to prevent the Weight of the cultivatorbeams when hung up from stretching the springs materially, thereby allowing the beam to fall.

In order to counterbalance, or partially counterbalance, the weight of the cultivator beams and shovels, I may employ springs 35, having their upper ends provided with links to adj ustably connect with notched plates 36, secured to the frame, and their lower ends connected with arms 37 of the pipe-boxes, to which are secured the clevises 88, that form part of the draft devices.

ThatwhichI claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with a frame, anda cultivator beam, of a crank pivoted upon said beam and adapted to lift the same by its rotation, and an automatic suspending device connecting said crank with said frame, and adapted, when said crank is rotated to lift said beam, to automatically lock it in its hungup position, substantially as described.

2. The combination with a frame, and a cultivator beam, of a crank pivoted upon said beam and adapted by its rotation to lift said beam, and an automatic suspending device connecting said crank with said. frame and adapted when said crank is rotated to pass behind and above the pivotal connection of said crank with said beam, whereby said beam is automatically held in its hung-up position, substantially as described.

3. The combination with a frame, cultivator beams, and double crank levers pivoted upon said beams and adapted by their rotation to raise said beams, of automatic suspending devices connected at their upper and forward ends with said frame and at their lower ends with said double crank levers, and adapted when said double crank levers are rotated to lift said beams to automatically suspend said beams in theirhung-up position, substantially as described.

l. In a cultivator, the combination with cultivator beams, and a frame, of double crank levers pivotally mounted upon said beams, and automatically operated links connecting said double crank levers with said frame, whereby as said double crank levers are rotated said cultivator beams are raised and automatically held in their hung-up position, substantially as described.

5. In a cultivator, the combination with cultivator beams, and a frame, of double crank levers pivotally mounted upon said beams and adapted by their rotation to raise said beams, and spiral springs connecting said double crank lovers with said frame, substantially as specified.
